APPARATUSFOR HOLDING WORK WEBS FOR TYPEWRITING MACHINES.

Application filed June 14,

The present invention relates to an improved apparatus for: holding a'web or worksheet to be used in connection with continw ous billing typewriting machines, one'form of which is shown in the patent to Wernery & Smith, No. 1,132,055, granted March 16, 1915. I

' Ina machine of this type, work-sheets or webs aroused in several layers or plies, each provided with .printed forms constituting one piece of work, which, when completed, may be torn from the continuous web. Carbon-sheets interleavedbetwecn the webs or plies are mounted on a carbonscarriage so, as to advance with the web toward the, platen while typewriting, and so as to'be'drawn back by thecarbon-carriage into the succeeding form-section of the web' afterthe lead ing form-section has been typed, fa'nd'prior todetachment from the web of such leading form-section. e i

To save time and trouble insubst'ituting a work-web of one style'for. that of another, the carbon-sheets, as shown in Unlted States Letters Patent to Fortin, No. 1,237,319, granted August 21, 1917, are not directly attached to the c'arbOn Carriage in the machine, but are attached to a plate'or holder which is detaehably secured tothe carbon-carriage so that a carbon-sheet-holding plate for any set of webs, with the carbon-sheets inter leaved therewith, may beremoved as a unit from the carbon-carriage, and another car; bon-sheet-holding plate, with carbon-sheets already interleaved with the plies of the desired set of webs, substituted therefor. Containers or cabinets for the several Webs and their respective carbon-sheet-holding plates and interleaved carbon-sheets have heretofore been devised to provide for a feed of the web from its container to the carbon-carriage of the type-writing machine, when the sheetholder shall have been placed on the latter,

The present invention has articular reference to an equipment whicl i comprises the above-mentioned continuous .billing apparatus as applied to a bookkeeping typewriting machine; and which involves ,a support, other than the machine-frame itself, for the carbon-carrier table, in order to allow clearance for, and access to, certain attachments commonly present on the rear of bookkeeping machines. Such other support for the carbon-carrier-table in turn involves means for determining a fixed relation of the same 1,922. seriai No. 568,093.

to the machine, so that the carbon-carriertable may properly connect to the platencarriage of the machine, and may move with the latter in letter-feed and return directions without 'bindiiig. Because of the size of bookkeepjingfmachines,a special stand therefor, easi1y rolled from place to place, is commonl employed; and, by providing the stand with centering means for the machine and for the'auxiliary carbon-carrier tablesupport, the correct relations of these may be assured." It will --be understo0d, however,

.that the invention is lnot confined to use in connection'with a bookkeeping machine or With a machine -staiidof any special type.

An object of their'ivention is the provision ota coinb'ined hol der or support for a table over which co'ntinuous "webs or work-sheets ma'y'b'eie'd to the platen, and means for supporting the work-web holder apparatus from thetypewriting-machine.stand, clear of the floor, and independently of the machine itself; and of means whereby the work-web holder apparatus is adjustable upon 'such combined table and work-web holder apparatus supporting device to permit any desired web in the work-web holder apparatus to be brought ,to set position with respect to the work-sheet table.

' A feature oft-he invention is a novel and simple arrangement of runways, on the combined support, forso carrying the work-web holder apparatus that the same may be slidably movedthereon to any selected position, or, if desired, may be removed entirely as part of the equipment, or be interchanged with other work-web holder apparatus containing different webs.

Other features and, advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a "iew in side elevation, partly cross-sectional, showingan Underwood bookkeepingmachine, with continuous billing attachment and stand therefor, and with the combined work-box holder apparatus and carhon-carrier table-support of the present invention connected to the stand.

I Figure 2 is a View in rear elevation of the work-box holder apparatus and carbon-carrier table-support shown in Figure 1.

Figure 3 is a detail view, in side elevation, of the latch for holding the work-box holder apparatus in selected position.

The frame 10 of the bookkeeping machine li G is shown supported"on lanner :11' of a stand having uprights 12 and cross-braces 13,

and having the feet 14 thereof provide'd'with" rollers- 15, wpeimie the stand with the' machine and associated parts-'- to be wheeled from place to place,

Sufficehere t0 say that the carbon-holder ofthe .Fortin patent comprises a plate 31, having secured thereto a. number of clips (not shown), each of which clips. engages and holds the rear end of a carbon-sheet, theseveral clips being stepped up, one from. another, more conveniently to enter and slide between the superposed web-plies.

In. the Fort-in patent, a single fan fold web is shown; the superposed plies forming the. web each being composed of detachable units bearing the same individual form or blank. Instead of thc'single web-comprised of fan-folded-superposed sheets or strips, several single strips or webs, as here indicated at32 above the platen, may be. employed; each. of the superposed webs being composed of such detachable. units.

The table25', near the -rear thereof, has a pairof depending brackets 34, each of which carries a roiler 35 which rides ona rail 36,

7 supported on brackets 37. The brackets 37 thus support the rear of the carbon-carrierbracket ;24 arev table, and the latter, by reason of the rolls 35'riding on the rail 36, is free to have letter-feed and return movements with the platenbarriage of the typewriti-n'g machine, to which it is connected at its forward end.

The right and left hand brackets 37 are connected at the rea'r'by rails 36 and 38, and at the front bya bar 39 carried by arms secured by screws 41 to the brackets. The bar 39 serves as a front support for the brackets37 on the platform of the stand 11, and is secured to the platform of the stand b screws 42. Each of the brackets 37 has ai so a front vertical reach 43, the lower end of which is turned outward laterally, as shown at 44 in Figure 2, and is turned in theshapepf a U around the corresponding rear upright 12 of the machine-stand. 11. By means of screws 45, the u shaped offsets of'thebrackets 37 are fixed to the uprights 12 of the machine-stand.

In assembling the brackets 3.7 on the stand 11, the bar 39 is first positioned and. screwed in place. The brackets 37 are then separately' brought to position against the outside faoesof the arms 40 of the bar 39, with their U -shaped extensions 44 embracing the legs-12 of .the stand. The screws 41 are thenapplied to secure the brackets to the. bar '39. The rear rails 36 and 38 are then set.in placeonthe brackets 37.. Thcreupon the'set-screws are tightened to fix the lower-front.- portions of' the brackets 37 tothe legs of the stand.v The setting of the bar 39 by the screws 42 determines the proper setting ofthe rail. 36:, so that t-he latter'may beparallel to the path. of movement of thecarriage on the machine-frame.

The brackets 37 include arms 46, which. are secured thereto by screws 47, and which extend downward and rearward, with an outward -fiare,,.indicated in Figure 2, from. the foot of the uprights 43 to the rail or bar 38. The bar 38 has secured thereto ears 48, which support and hold a rail 49, extending lengthwise. of the stand. At the upper ends of the brackets 37, other brackets or ears are held by means of screws 51. The cars 50 support and hold a rail 52, extending lengthwise of the stand, parallel to the rail 49.. I

The rails 49 and 52 serve. as runways, on which the workwebholder apparatus is supported for adjustment laterally, with respect to the carbon-carrier-table 25, to permit different tiers of web-holders to be selectively positioned for use of the desired web. The frame of the work-web holder apparatus or standard comprises. four bars or uprights 53. having offset ends. The offsets 54v at the. lower ends of the bars 53 are connected by a tie or cross piece 55. Secured to the crosspiece 55 are cars 56, on each of which is mounted a roller 57, grooved to ride on the rail 49. At their upper ends the bars 53 are first ofi'set forward, as indicated at 58 in Figure 1, and at the forward ends of the offsets 58 are lateral ofi'sets 59, on which is secured a tie or cross piece 60. On the cross-piece 60 are a pair of rollers 61, which are held by the weight of the work-web holder apparatus, against the forward face of the rail 52, so as to ride thereon. A pair of guards 62, secured to the cross-piece 60, extend around behind therail 52, to prevent forward displacement of the upper end .of the work-web holder apparatus.

In Figure 2, two banks'or tiers 63, 64 of web-plies are shown. The bank'of web-plies 63 is shown as comprising four web-plies 65, 66, 67 and 68, whichare superposed and are led from supply-rolls 69, 70, 71 and 72, respectivelypto' the carbon-holder 29 on the carbon-carrier-ta-ble, and as also comprising three other web-plies 73, 74and 75, which are superposed and led from supply-rolls 76, 77 and 78 to the carbon-holder on the table, where'they are superposed'on the web-plies 65, 66, 67 and 68, to form a web in seven layers, between which carbon-sheets "are .interleaved. atthe carbon-holder, the whole being then led to the platen, for the printing operation. The bank of webs 64 also has seven web-plies led from rolls to a carbonholder 29 in the same manner as the webplies which form the bank 63. It will be understood that the forms on these latter webplies may be different from the forms on the web-plies of the bank 63. and the bank 64 may be substituted, at will, for the bank 63 by interchanging the carbon-holders 29 and 29, as above noted. The carbon-holder not in use, with the web-plies secured thereto, may, as shown in Figure 1. be held in a trough 79. carried on arms 80. projecting rearwardfrom the cabinet-standards 53. below the lower rear supply-rolls. In effecting the interchange, the work-web holder apparatus is slid on the rails 49 and 52. to move one bank of web-holders out of center position, with respect to the carbon-carrier-table, and to move the other bank into such center position.

To hold the work-web holder apparatus in proper position on the rails 49 and 52. for use of the selected bank of web-plies. a lock is provided. This look, as shown in Figure 3. comprises a dog 87, pivoted at 88 to the offset 58, at the upper end of the left-hand (Figure 2) standard The rail 52 has two notches 89 and 90 therein, to receive the nose 91 of the dog. In Figures 2 and 3, in which the work-web holder apparatus is positioned for use of the left-hand Figure 2 bank of plies, the dog 87 is in engagement with the notch 89. When, however, the work-web holder apparatus is moved to the left, for use of the right-hand bank of webplies, the dog 87 comes into registration with the notch 90 at the left-hand (Figure 2) end of the rail- 52." A -leaf 's'pring-92' causes the dog automatically toenter the desired notch when the dog comes into registration with such notch, upon suflici'en't movement of'the work-web holder ap aramMn-em or the otherdire'ction'; and the spring 92 serves to hold the"do'g*in the selected notch against accidental displacement. The 5 work-web holder 'apparatus' is unlocked" from the rail 52 by means of a finger-piece 93 on the dog. Oneofthemiilti plywebs'is-shown at 81 asfled'over'a rod 82'at the-rear of the table 25 thence-forward over 't he ftable 25 and over'arod'*83;'carried brackets 24 at the rear of the platen. Fr'oi'nthe rod 83 the web i's'fled'downwardf around the 'platen, and tn mgejupwaraacross "ad-able 84' on the platen-carriage. In order that the'forward web-seetioni'naiy feed freelywith the platen, unresist'ed bythe'supp'ly-rolls, a slack is prov'ided in the web at- 85,-between rollers "96 at the-"top of the" work web fholder apparatus, and rail 82 ou thetable'; this {slack being ef feeted' byi'aforward and then a rearward movement 'ofwhe carbon-holder,- after the leading i web-section hasfbeeir typed and before typingof the mexeweb-section. For gripping the web-plies, to draw off from the rolls a length of web sufficient to .form the slack 85, a clamp 86, which may be of wellknown form, is provided on the carbon-holder 29. After the slack 85 has been formed, the clamp 86 is released, so as to be ineffective when movement of the carbons, relative to the web-plies, is desired.

It will be noted that, by reason of the mounting of the work-web holder apparatus on the brackets 37, the work-web holder apparatus is movable as a unit with the typewriter-stand from place to place. The workweb holder apparatus is, however, readily detachable from the brackets 37 when not desired, or when another work-web holder apparatus is to be substituted therefor, by movement of the work-web holder apparatus off of the ends of the rails 49 and 52. C01- lars or stops 94 and95 on the rail 49 prevent accidental throw of the work-web holder apparatus to a position Where its supporting rolls will leave the rails. These collars or stops may also serve to assist the dog 87 in finding its desired notch 89 or 90. For instance, when the work-web holder apparatus is thrown to the stop 94, the dog may register with the notch 90, and, when the Work-web holder apparatus is thrown to the stop 95, the dog may register with the notch 89. To place or remove a work-web holder apparatus, it is simply necessary to remove one of the collars 94 and 95.

It will also be noted that. in supporting the carbon-carrier-table on the brackets 37, instead of on the machine-frame, and 1n so shaping the brackets 37 to provide considerable clearance between the same and the machine-frame, ample space is a-llowed for the attachments. (not. shown). but usually present. on the vearof the limo eepingmachine, and ample provision is made for eesy access to such attachments.
